Yes, both should be the same.

What tire size are you running?
...noting that the bigger the tire the worse this situation becomes.

I am running stock tires. I think the whole problem is the metering rods and springs. Ordered the set today so now can't wait for them to get here.

Thanks Shawn.

Just got the metering kit and put in the rods and springs and it runs like it should. Now I'm going to play with different rods and springs.

Cool...now you can see how it does and then decide on swapping gears...glad you got it figured out.

springs are depending on how much vacuum your engine makes. The strongest ones are for stock vac, weaker ones get swapped in as vac goes down. I think below 10" or so you need to go to a lighter spring.

The rod sizes are the first way to change rich/lean mid-throttle. If your plugs are white go a size smaller on the rods, if they are dark go a size bigger.

If you can't get them to be tan changing rods, then you need to change jets.

Thanks Lattimer.
